PETER E. MILLER AND JOHN H. sTmeER, OF KILGORE, OHIOi .NUT-LOCK;

SPECIFICATION forming part Of LetterS Patent NO. 733,245, dated J uly 7, 1903.

Application filed March 16, 1903. Serial No. 148,032. (No model.)

To ctZZ whmn it may concern:

Be it known that we, PETER E. MILLER and JOHN H. STINGER, citizens of the United States, residing at Kilgore, in the county of Carroll and State of Ohio, have invented certain new and useful Improvements in Nut- Locks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to nut-locks; and it consists of the features of construction and combination of parts hereinafter fully described and claimed.

The object of the invention is to provide a nut-lock which is of such construction as to simultaneously and securely look all the nuts used in connecting the fish-plates together'at the meeting ends of rails.

In the accompanying drawings, Figure l is a perspective view of the meeting ends of adjoining rails, showing the application of the invention. Fig. 2 is a cross-section thereof, and Figs. 3 and 4 are similar views showing a modification.

Referring now more particularly to the drawings, the numeral 1 denotes the meeting ends of two adjoining rails; 2, the fish-plates, disposed on opposite sides of the rails; 3, bolts projecting, in accordance with our invention, in opposite directions through the rails and fish-plates; and 4, nuts applied to said bolts.

Arranged on opposite sides of the rails and bearing against the fish-plates are lookingbars 5, provided with apertures 6, the walls of which are adapted to embrace the nuts, and hence the bolts, and thus prevent the nuts and bolts from turning.

Arranged on opposite sides of the rails are clamps or retaining members 7 7, which are provided at their upper or free ends with apertures 8 to receive studs 9 on the lockingbars, by means of which they are held in connection with said bars and prevented from shifting. These clamps or retaining members are bent downwardly to fit the upper sides of the base-flanges of the rails and thence extend under the flanges and have their lower ends pivotally connected by a pin or bolt, as at 10. A tie rod or bolt 11 passes through apertures in these clamps and is formed at one end with a slot to receive a split tapered key 12, by means of which the bolt or rod may be drawn upon to force the clamps into engagement with the locking bars and hold the latter securely in looking position. By this constructionit will be seen that all the nuts connecting the rails at their meeting ends will be simultaneously and securely held from turning and that by the described construction of the clamp or retaining device the locking members may be readily and quickly applied and removed.

In the construction shown in Figs. 3 and t the clamps or retaining members consist of metallicstrips arranged on opposite sides of the rails and secured thereto by a bolt 14. The strips are then bent at right angles to form a horizontal portion 15, which bears against the upper surfaces of the fish-plates and locking-bars and are finally bent at their lower or free ends to form the clamping or retaining portions 16, which bear against the sides of the locking-bars. The mode of application of these parts will be apparent from the foregoing description.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily apparent, it is thought, without requiring a p more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

It will of course be understood that the nutlock may be applied to the bolts and nuts of machine parts and wherever a device of this character isuseful or required.

Having thus described our invention, what we claim as new, and desire to protect by'L'etters Patent, is-

1. In a nut-lock, the combination with the meeting ends of connecting rails, and fishplates on opposite sides of said rails, of bolts passed in opposite directions through the rails and fish-plates, bars bearing against the fish-plates and engaging the heads and nuts of the bolts, a clamp bearing against each bar to retain the same in position, anda fastening for simultaneously securing the two clamps in position, substantially as described.

2. In a nut-lock, the combination With the meeting ends of connecting rails, and fishplates on opposite sides of said rails, of bolts passed in opposite directions through the rails and fish-plates, bars bearing against the fish-plates and engaging the heads and nuts of the bolts, clamps bearing against the fishplates and projecting beneath the base of a rail and pivotally connected, and means for drawing said clamps together to retain the bars in position, substantially as described. 3. A retainer for nut-lock bars comprising two members pivotally connected and adapted to bear at their free ends upon the bars and to engage and project under the base of a rail, and means for drawing the said members together, substantially as described.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
